e206cebf59 Change v_usecount & v_writecount from a short to an int. As shorts they 
can and will overflow on large machines - especially on machines with
filesystems with lots of files (like netnews servers), and the result
is a "free vnode isn't" panic or worse.
This fixes one of the causes of these panics that I've been experiancing on
wcarchive.

46268a606f Revert to previous calculation of vm_object_cache_max: it simply works 
better in most real-world cases.

8dec8ed218 Nit: according to the Harvard code, it is necessary to clear the timestamp 
counter before loading the performance-monitor control register.  I'm
not sure I believe this, but we'll follow their lead for the moment.
As a result of this commit, the performance-monitoring test program that
I wrote now works (the program will find its way to share/examples).

8fb3332429 Fixed the unit numbers of the devfs `fd' devices. 
Made the devfs `fd' devices bug for bug compatible with the ones created
by MAKEDEV:
- ownership is bin.bin, not root.wheel, except for std*.  The devfsext
  interface doesn't seem to allow specifying the ownership of /devfs/fd,
  so it's still incompatible.
- std* aren't links to fd/[0-2].
